1. Introduction
Online photo processing system software is a commercial product for the normal user to get digital
photo printing service. This document is provided for the requirement and design specification so that
developer can get the clear idea of the system and also the design specification of the system. It
contains also prototype UI which is very useful for the customer to know about front-end view.
2. Business requirement
Printing digital photos through online print shops is significantly gaining market. Typically, print
shops only offer payment via credit card and automatically apply standard picture settings that not
always produce acceptable results. To guarantee professional service, higher quality and flexible
payment options, the following procedure (to be automated) could help.
A user starts the processing by logging (user name and password) in the system. If the user is new
then he/she has to be register to enter in the system. After that, user will place a new print order by
uploading his/her picture files and by specifying the desired print sizes and qualities. Immediately,
the system checks whether the uploaded files are compatible picture files and whether the pictures'
resolutions are suited to the specified print sizes. In case of problems, the user is asked to modify his
order. This procedure goes on until no further problems can be detected, in which case the order is
forwarded to a photo editing expert, which is in charge of checking the aesthetic quality of the
pictures. If the expert has some comments, he/she fills in a form with appropriate feedback and (if
required) suggests possible editing operations. After that, the user can comment the provided
feedback via the shop's Web site and accept/deny the suggestions. Based on the user's decisions, the
expert applies the accepted modifications and fixes the final cost. If the expert has no additional
comment, he/she just fixes the cost according to the price list. Once the cost of the order is known,
the system sends an email with the required payment instructions to the user and, also, forwards the
pictures to the print department. The user can choose between online payment via credit card, money
order or bank transfer. Credit card payments are directly supported and processed by the shop's Web
site, while the two other options are not under control of the system, which thus keeps waiting until
the payment occurs. After completing the payment terms, system will ask for the shipment address.
In the meantime, the print department prints the pictures and prepares them for shipment. Once the
payment has arrived, the prints are shipped, and the user has one month to provide his feedback (and
to close the order) before the process terminates automatically.

6. Web Design Project
The Use case diagram of the online digital photo processing system contains the scope of the system,
the list of system functionalities and the total vision of the possible interactions between the system
and the actors of this system. The main actors identifying here are:
i) Customer: Customer represents as the primary actor for this system. The printing
company offers the digital photo printing service online for the customer in different
location.
ii) System operator: The general operator and the administrator are the two actors and these
are the generalizations of system actor.
General Operator: This type of actor supports the system to complete the main flow of
events to achieve the goal. It takes care to delivery the shipment order to the requested
customer.
Administrator: Administrator of the system is responsible to several interactions with the
system to reach the objectives. As an example administrator can delete the customer order
at any time with proper reasoning.
iii) Database Server: A Database server act to store the customer authentications information
and it’s also added the new customer’s information when a new customer-user registration
occurs.
iv) Web Server: Web server take care of new user registration, user authentication, ask
picture, check picture, checking image quality, fix the final cost, automated email and
collecting shipping address.
v) Photo Printer: Printer is responsible for process printing and prints out photo to delivery
this to the requested customer.
Based on the above use case diagram we can identify the following groups of main types of
activities:
i. Customer starts the processing by logging in the system. In case of a new customer, he/she
has to be register to enter in the system.
ii. Customer will place a new print order by uploading his/her picture files with specifying the
desired print sizes and qualities.
iii. The system checks the picture files with respect of compatibility and resolution suited to
specific print size. In case of problems, the user is asked to modify his order. This procedure
goes on until no further problems can be detected.
iv. The expert applies the accepted modifications and fixes the final cost.
v. The system sends an email with the required payment instructions to the user and forwards
the pictures to the print department.
vi. Credit card payments are directly supported and processed by the shop's Web site.
vii. After completing the payment terms, shipment address will be collected. The print
department prints the pictures and prepares them for shipment.
viii. Once the payment has arrived, the prints are shipped, and the user has one month to provide
his feedback and after that the process terminates automatically.

Figure 2.4: UML- Class diagram for on-line photo processing system
Using the above class diagram we represent the vocabulary of our online photo processing system. It
is built and refined when system is developed. Each class description consists of a class name, state
variables, reference variables and methods. We make a clear distinction between variables containing
the state of an object and variables that express which other objects a given object knows. A class
description defines the types of each variable as well as a signature for each method.
The objectives of class diagram are.
Names and models concepts existing in the system.
Specifies collaboration paths.
Specifies the basic logical schema.

4. Framework of the development
4.1 Logical architectural diagram
Figure 3 : Logical architectural diagram
It is basically the coding layer of our application. There are there layers between User Interface (UI)
and Database. Those are:
Mohammad Jannatul Ferdous -7-

9. Web Design Project
Façade Layer: It contains the all methods/ function of the application to update, delete and insert in to
database. It is directly connected to the User interface and also business layer. Sometimes it access
Data Access Layer (DAL) directly if the functionality does not require any business logic.
Business Layer: It contains the whole business logic of the system. If developer requires any changes
in the business logic after develop the software then they will only change on this layer. They do not
need to change the whole application. BL connected with DAL and Façade Layer.
Data Access Layer: It is used to access data from Database and only know the query or stored
procedure of the database to retrieve, modify data like SELECT, UPDATE.
Base Layer: It contains the all configuration setup of the system and base class of the different layers.
4.2 IDE and tools
Visual Studio.Net 2005: We have used Visual Studio.Net 2005 as an Integrated Development
Environment (IDE) to develop our prototype.
Visio 2003 & UML 2.0: We have used Visio 2003 to draw all design with UML2.0 notation.
SQL Server 2005: We have stored our sample database in to SQL Server 2005 Express Edition

5. Prototype of the System (Graphical User Interface)
We’ve made to make the new users to understand the Qavi online photo processing system easily.
Thus it is a dynamic web page customers will easily be able to upload their digital photos through
CD drive, floppy drive, external devices or hard drive. Also be able to create their own account,
album and upload pictures to that album and can save them. And could order them according to his
choice by my given sizes with price. And then he/she could be able to proceed to the check out. Now
we’ll explain the total system point of users view.
We’ve created the header & footer because we will need to use them throughout the whole
application. In this page we have got Home, Register & Login link button I’ll use Logout in the other
pages, Home button to call the home page, Register to register as a new customer & Login for the
users who have already registered. In the Footer we’ve also got some following link button Contact
us, Pricing, Help, FAQ. Contact us to get our e-mail & web address customers will be able to mail us
as well. In the pricing page we’ve given some price list with respect to shipping time, paper size and
quantity. And I made another page for help there we’ve given some problems customers might face
with solution. So the following is my home page with these actions. We’ve also given two buttons for
Login & Register. (Help and FAQ are under construction).
Figure 13: Home page of the online photo processing system
